Shouldn't a time travel question start with posting the answer? Just for legitimacy?

If we can develop something faster than the speed of light, there will be time travel. I doubt that ever happens.

if it was invented later we would know about it now due to people not being able to keep their mouth shut.

I would think of they were able to travel back in time, they would altar a timeline that we are not currently living in. We would never know.

Hawking staged a time traveller party and sent publicized invites after the fact, which is brilliant and hilarious. No one attended. Now you could argue that people aren't allowed to let you know they are time travellers, but that would imply the technology is not wide-spread because there's no way you get that sort of discipline over a large group of people.

We know we need to look to the stars for these answers

I saw something the other day that said not only would you have to worry about what was in your location when you went back in time, but also where the Earth would be. Given that the Earth is revolving around the sun and the sun is revolving around the center of the Milky Way, just by going back in time a few minutes, you'd end up basically warping yourself into vacuum of space. So not only would you have to master time travel, but you'd also need to somehow tether your location to the point in space as it exists in the past (or future). Mind blowing stuff...
Not only is the earth rotating and revolving around the sun, and the sun revolving around the galaxy, but the galaxy is also moving through space. And not only that, but space itself is expanding. What is the frame of reference if everything is constantly moving and changing?


I think this relates to the idea that time travel to the past might one day be possible, but only back to the points in time after the machine is turned on, and only to that location. Like we have to create a portal through spacetime and we couldn't just go whenever and wherever.

Time is linear, but aren’t all linear things relative to the plane in which they’re measured?

I like to think of this occasionally. But what if it isn't linear? What if everything is happening all at once. What if every moment exists all at once, and always. so every instance exists perpetually in maybe different planes of existence. And what we perceive as moving linearly through time is just us moving through these different planes. Much like a movie exists only as separate frames. All those frames always exist as a whole, but we only experience them at a set pace.

I once took off in Atlanta at 3:05 and landed in Gulfport at 2:02. shite was creepy. I hid in the airport bathroom for a while so I wouldn't run into myself and creates some sort of temporal anomaly.

So what you're saying is that time travel may have been discovered at some point in time and there's possibly a whole lot of frozen bodies that may one day come falling out of the sky in ones and twos. (Or already have and we didn't recognize them.)
